    Subject: Problem with instrument panel fit
    --> RV-List message posted by: "Steve Struyk" <rv8striker@hotmail.com> Anybody have this problem? I finished my panel months ago and trial fit it several times with the top skin clecoed on. Everything fit and all holes around the perimeter of the panel lined up. Now with the top skin riveted on, the windshield and canopy done, I tried to install the completed panel. Some of the mounting holes are off by half a hole. I assume the top skin, in the process of riveting, changed the geometry of the panel opening. The fix will be replacing the nut plates with floaters and opening the holes a bit but what a pain. In retrospect I'd put floaters there in the first place. Something to think about if you have not done yours yet. Steve Struyk RV-8, N842S St. Charles, MO

Here we all are discussing the standard way to construct these planes and forgetting altogether the true nature of experimental and that is to try out new ideas. What if its discovered that we could use pop rivets on 50 75% of the plane and only loose 5-10kts. That would be a huge time savings for a small price in speed. So here I am laughing but not at the original poster, instead at the rest of us who scoff at someone who asks what if. Chuck, my suggestion would be at the minimum to have flush rivets on the leading edges.

    --> RV-List message posted by: "Aircraft Technical Book Company" <winterland@rkymtnhi.com> I've been looking over Randy Pflanzer's annual inspection checklist for vansairforce.net and I see he specifies lubrication of all the rod end bearings on the elevator, rudder, and ailerons. First, I didn't know that these bearings need periodic lubrication, and now assuming they do, what is everyone using for lubrication? Thanks, Andy

    Subject: Re: Blasphemy or what?
    --> RV-List message posted by: Charlie England <ceengland@bellsouth.net> The Thorp T-18 was designed for construction with pulled rivets (and pre-dated everybody else by about 25 years with matched-hole tooling ). T-18's fly very well, with handling similar to RV's & cruise speeds that are almost as good. If flush head pulled rivets were used & the heads filled with one of the new hi tech fillers, the only difference from a regular RV should be a few extra pounds of rivet weight. It's not hard to see the attraction for someone without easily accessible bucking partners.

    --> RV-List message posted by: "Zeidman, Richard B" <richard.b.zeidman@boeing.com> RV Listers, Just a reminder that the wings, bulkhead and main landing gear from my RV6A that was in a forced landing accident are on auction on E-bay and the auction ends in about 24 hours. I believe that it would be a fairly easy repair due to the pre-puched skins that were used in the original construction.The reserve price of $500 has been met, but I think the fuel tanks alone are worth that much. I've decided to rebuild with an RV7 so not too much would fit. If you have any questions, I can be reached at 610-591-8747 (W) or 610-358-1727. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=45601 88651&category=63679&sspagename=WDVW Thanks for looking!

As Tom mentioned, you need to make sure the instrument panel is in there when you rivet the top skin. I had a very similar problem when I drilled the holes for the F-821PP skin - afterwards the instrument panel didn't fit. I ended up buying the parts to the left and right of the panel again, and re-drilling the holes and installing the the nutplates. I had to cut out about 1/4" at the top. -- Mickey Coggins http://www.rv8.ch/ #82007 finishing do not archive

    Subject: Re: Blasphemy or what?
    --> RV-List message posted by: Kevin Horton <khorton01@rogers.com> But, pulled rivets aren't as strong as solid rivets (unless you use the expensive CherryMax rivets, which have fatigue life issues). So, either need to decrease the rivet pitch (which won't work if you have a pre-punched kit), or up the size to 1/8 inch (if that gives equivalent strength to 3/32 solid rivets). And this would only work if you knew that you would never want to sell the aircraft. You would have a very hard time selling an RV with a substantial number of pulled or round headed rivets.

BTW most of the aircraft that use pulled rivits do use 1/8" In the early 1970's I built an all metal aircraft called a Mini Coupe it used all steel cadium plated 1/8" pop rivets. I had an engine failure with the VW engine that was in it and ended up upside down in a field. Tore metal everywhere but not one rivet pulled loose. I rebuilt it and it was still flying up to about 5 years ago when the current owner made a hard landng with it. I know that the person I know that had an RV-3 with "round head rivits" did not have a problem selling it at all. Jerry do not archive

His data showed that the joints riveted with the AN470 round head rivets were only about 82% as strong as joints riveted with AN426 flush head rivets. I archived his description of the test and the results at: http://www.kilohotel.com/rv8/rvlinks/marvelrivets.html The following reference suggests that the strength of blind rivets vs solid rivets depends significantly on where the mandrel breaks (and by inference, whether the mandrel is locked in place). http://www.roymech.co.uk/Useful_Tables/Rivets.html If the mandrel is designed to go all the way through the rivet, and be retained in place (like the expensive high-strength rivets from Cherry), then you may achieve a higher strength than with solid rivets. If the mandrel doesn not plug the hole, or if it is not locked in place, then the blind riveted joint would be weaker. So, if you use high-strength Cherry rivets, you may end up with a stronger structure. But, no one would use the expensive Cherry rivets everywhere, due to cost. And, there have been problems with poor fatigue life on some high strength Cherry rivets. I recall a helicopter crash many years ago that was attributed to a repair that failed due to poor fatigue life of Cherry rivets. If the aircraft was designed for blind rivets, then I have no concerns. But, if you just substitute blind rivets you now have a very different structure than the designer assumed. You have no idea what loads the structure can support. The designers calculated strength, static load tests and service history are no longer relevant. You would have an aircraft that looked like an RV, but no one would know what loads the structure could support. I would expect that knowledgeable buyers would rather have an aircraft that was built the way Van intended. Kevin Horton RV-8 (finishing kit) Ottawa, Canada http://www.kilohotel.com/rv8

    --> RV-List message posted by: "Tracy Crook" <lors01@msn.com> FWIW, I seem to recall that Cessna either tested or calculated the effect of using flush rivets on one of their planes (a recip engine, can't remember model) and found a 5 - 6 knot improvement. Might make more difference on a faster plane like an RV. Tracy Crook (Blasphemous rotary engine installer, more than 5 kn faster : ) do not archive

    Subject: Re: lubricating rod end bearings
    --> RV-List message posted by: "Martin Hone" <mctrader@bigpond.net.au> Hi Andy, I lubricate the rod end bearings annually, using one of the motorcycle chain lubes, as the lube comes out very thin and gets into the bearing before setting up as a semi solid. The is a range of this stuff, using teflon or moly-disulphide (?) available from bike shops. One I use is Maxima Chain Wax. In areas where dust is likely to be more of an issue, I use a teflon-based spray lube so that dust doesn't adhere to the bearing and work its way inside. I lube the external aileron and flap bearings every few months this way. FWIW.. Martin in Oz

    Subject: Re: RV 7 Access Panel
    --> RV-List message posted by: Phil Birkelbach <phil@petrasoft.net> Just to play a little Devil's advocate. Remember that all the skins on this bird carry some load. Consider the plate that you use for the recess as a doubler. It needs to carry the load of all the metal that you remove for the access cover. I'd go with a thicker piece of metal, maybe 0.040 or even 0.062 as the recess plate. And don't spare the rivets and screws. Just some thoughts I'm not trying to stir anything up.

    --> RV-List message posted by: Chuck <chuck515tigger@yahoo.com> Walter, You can find a few more good laughs that I've posted over the last few years (different email addresses, but still "Chuck"; prior to that I was just a lurker). I've built/re-built my share of RV-4's and last weekend drove up to Monroe, Wa., picked-up another RV-4 kit, and drove it home. This kit was started in 1988, but only the tail feathers are complete (less the glass work). It took me a little over 2 years to build my first RV-4, I was in a rush to fly. This kit I'm gonna take at an easy pace. I've had the pleasure of helping other folks with their RV's and re-built 2 Sonerais. I like Sonerais a lot, but after getting to fly a Rocket... I wanted one. I'm a family guy with a modest job so the best I could do was the RV-4. I've modified my RV-4 with 80% span ailerons (first I made 'em 100% great roll-rate, but I had a helluva time seein' my short/narrow dirt strip on final so I went 80% with air-brakes and that did the trick), VG's, and inverted fuel/oil (Ly-Con IO-320 160 hp) 'cuz I like aerobatics a lot (I won first-place in the Basic division at IAC's Delano Contest a couple of years ago in my RV-4 that's when I started tweekin' on my 4). I've seen your website, nice work. Don't worry this won't get archived 'cuz it's attached to yours that states DNA.

Since you did not include "do not archive" in your post, this question will forever be linked solidly to your name. Over the years, I'm sure it will garner many a good laugh.

    Subject: Oshkosh
    --> RV-List message posted by: "Phil Sisson, Litchfield Aerobatic Club" <sisson@consolidated.net> RV gang.... If you are going to Oshkosh, you may want to consider a stop at our little small town airport. 3LF http://www.litchfieldil.com/airport/ take a look at the photography, the young eagle links, the pilot info and then.......... stop over here for a night. Gas is guaranteed at $2.85 a gallon (self service, like at the car gas stations). We have a courtesy car ( old chevy, not pretty. but runs good) No, the gas price is not very good, but it is the best we can do and it will be this price on return trip also. We are about 340 or 350 miles straight south of Oshkosh.. On field camping, and motels within 1 mile walk. restarants, bars, Free overnighting and Admin. bulding will be Kept open for rest rooms and what ever. Sleep in there if you want...... Pass this information around to the other Matronics lists if you dont mind. Bring your tie downs and ropes that you will need in Oshkosh just in case we would have more than eight planes here. There is plenty of grass for yie downs....... Also Chapter 61, Acro contest will be going on that weekend at Salem Illinois.(about 45 miles southeast) Feel free to stop in there for some great competition and partying.... Phil RV6 flown and tore down now for painting............ Sure wish I had a Pitt's to Fly..........
